While waiting for my front axle bearings and seals to arrive, I decided to perform a bunch more maintenance items on my 78 FJ40. Air Randy suggested extending my axle vents in another thread, which is an excellent idea. I did some searching on MUD and here and did not find clear direction. Some say to rip off the vent housing, spring and flapper and run a 3/8" line up in the engine bay. I assume I need another check valve or vent at the end of the line? What is the best/easiest method of extending the front and rear axle vents?
